Charmed

The X-Files

Hi!
There's a question that interest me very much. It's the question which series you like most? For this I chose four series: Angel, Buffy - the vampire slayer, Charmed or The X-Files. I chose these series because I think they belong to the category "mystery" or they have at least something to do with mysterious things.
Now it's on you to vote, which is best.
I'm looking forward to the result....

As much as I love Buffy, I'm more into Charmed so I voted for that Its not as well written as Buffy and has a bad habit of inconsistencies but its a fun show I dont like Angel that much (tho I still watch it) and X Files hasnt been as good as it used to be for years now
